STUART GWYNN, OF NEW YORK, N. Y., ASSIGNOR TO AMERICAN METAL- INE COMPANY, OF SAME PLACE.

Letters Patent N 101,862, dated April 12, 1 870; antedated March 30, 1870.

IMPROVED COMPOSITION OI MATTER, CALLED METALINE," FOR JOURNALS, BEAR- ING-S, 8L0.

The Schedule referred to in these Letters Patent and making part of the same.

To all whom may concern:

Be it known that I, STUART Gwrnx, of the city of New York, in the county of New York and State of New York, have invented a new Composition of-Matter, which I denominate Metaline No. 2, designed for the purpose of journal-boxes, journal-box linings," and other similar articles having surfaces that are intended to be subjected in use to friction.

The nature of myinventiou consists in'combining ivory-dust and spermaceti, or their equivalents, upon t-l1e principles and in pursuance of the method fully described and illustrated in the specification annexed to my application for Letters Patent for a process for making metalire, filed in the Patent Otfice'simultaneously herewith, and to which reference is made, wherebyl produce a-composition of matter having 'such properties and conditions that so little friction will be caused, and so littlelheat developed in the practical use of the above-named articles made of it, in machinery and elsewhere in the arts, that the necessity for the application of oil or any other lubricant to their surfaces is entirelyohviated.

To make this composition of matter, I take of ivorydust eighty parts by weight, and of spennaceti twenty parts. The ivory maybe purchased in the form of scraps, saw-dust, turnings, &c., and reduced'to powder by grinding, which may be best done in a buhr-mill.

The spermaceti is to be intimately mixed with the ivory-dust, which will be best accomplished by grinding them together in a suitable mill for some time, say two or three hours. The mass is then to be subsides spermaceti, its equivalents for the purpose in-. tended, may be used. So also the relative proportions of the ivory-dust and spermaceti, or their equivalents above stated, may be varied within the limits of the process hereinbefore referred to without departing from the spirit of my invention.

Claim I claim as my'iuvention- The manufacture or preparation of a composition of matter which I denominate Mctaline No. 2, when the same possesses the properties, and is compounded .of the ingredients or their equivalents in the proportions, by the process, and for the purposes set forth.
